Research and development on the current world's fastest structured light 3D system, both hardware and software. The system achieves real-time data acquisition, processing and visualization. The frame rate achieves 120 fps with high resolution of 640*480, using an Intel Core 2 Duo Quad Q9650 processor. This novel system employs structured light, pattern design, gamma distortion correction, noise analysis and reduction, motion compensation, filter design and other techniques (Visual C++).

Jun.2008-Feb.2009

Research and development on a cell scanner, both hardware and software (control system). The scanner employs three motors and a camera to automatically find qualified cells by employing image processing techniques. The qualified cell will be picked up by a needle straw (.Net).

Jan.2008-Mar.2009

Research and development on a high accurate multi-view hybrid 3D scanning system. The system is based on noise model and combines the techniques of structured light and stereo vision. The reconstruction achieves a 26 times reduction in error, compared to traditional structured light system, especially in the albedo/depth high contrast area. The system employs structured light, stereo vision, noise modeling/analysis and other techniques (.Net). (Also see the hybrid 3D system at 3D Imaging Lab)

Jan.2007-Dec.2008

Research and development on the world's first practical depth-detailed 3D contactless/touchless fingerprint live scanner and its post processing algorithm. The current scanner is portable, and takes 0.7 second to scan one 3D fingerprint with 5 million pixels. The 3D fingerprints are detailed into level 3, where even pores on fingers are clear. The 3D fingerprint is further unraveled into 2D to match NIST 2D fingerprint standard. Distortion in traditional 2D fingerprinting is greatly defused. The system employs pattern recognition, de-blurring, data fusion, motion compensation, filter design and other techniques (C++). (Also see the 3D fingerprint scanner at Flashscan3D,LLC)
